As silly as this might sound, I've been using Paint.NET for close to a decade now, and I've always made every shape I needed myself. With the release of 5.0, I finally decided to get some custom shapes. So far I've used them way more than I thought I would, either by themselves or as a starting point for more complex designs. Thanks for making them, and if you decide to make any new ones, I can safely say at least one person would use them. Keep at it!
